This invention relates to corn .pop rs and I it has for its object roviding a'suita le corn popper to be heate by electricity. Another ob] ect of the invention is to' provide suitable ,5 means for properl stirring the corn as it is.

being heated and orbringmg the unpopped corn in position to recelve the maximum amount of heat. Other objects of the invention will be apparent from a consideration of the accompanying drawings and the following description thereof. p

y'Of thefdrawings, Fig. 1 is a .central sectional elevation of the corn popper; and Fig. 2 isa section along the line 2--2 of Fig. 1. The popper comprises a vessel 5 supported by legs 6 and havin a handle 7 and a cover 8. The cover is'a apted to be entirely removed from the vessel 5. Thestirring-mechanism comprises a crank'9 which is mounted in bearings 10 in the cover. The crank has an arm 11 adapted to coact without interlocking, with an arm 12 on the stirrer 13. The stirrer is mounted in bearings 14 and 15. The bearing 14 is mounted in a cross the bearing 15 is fixed to the bottom ofthe vessel. A spring 19 yieldingly` holds the lower end of the stirrer down in the bearing 15.

When the corn is to bejpopped, it can be placed in the vessel 5 b simply lifting the cover and crank 9 from t e vessel. The cover is then returned and the corn stirred as it .is bein" heated. As the corn pops, it flies upwardly and the unheated corn passes down thev sides 17 of the vessel to the bottom 18 which receives the maximumamount of heat.

The heating system comprises a heating coil 20 supplied with electricity by means of a plug 21 and acord 22, the cord being connected, in an ordinary manner, with any suitable source of electric current. The coil is mounted on an asbestos plate 23 andheld in position by means of flanges 24 projecting upwardly from .the plate. Encircling the coil is a band 25 of asbestos or other suitable insulation and, as the flanges 24 extend slibstantially up to the bottom 18of the vessel, the heat is substantially all transmitted to the vessel, waste being prevented by the varibar 16 in the upper part of the vessel-andY ous pieces of insulation. Tolimit the amount of heat which may esca e downwardly through the insulation, a s eet 26 of lnsulation is provided, supported by lugs 27, between the heater and the support of the POPPGT- It will thus be seen that I have provided a corn popperwhich can be conveniently lled and emptled and, by means of which, the corn can be thoroughly stirred at all times wlthout.- disturbing the popper itself. The popperis so arranged that the unpopped corn 1s contlnually. working downwardly as the lighter poppedV corn moves upwardly and,` thus, burning of the corn is'prevented and uniform distribution of the heat is provided for. Also, the arrangement is such that substantially the entire' amount vof heat from the electric heater is transmitted to the corn. Inasmuch as the vessel is metallic and, hence,

a good conductor of heat, the heat is con- -journaled in said bar and extending downwardly with its lower end journaled in the bottom of said vessel, a loop in said shaft lmmedlately aboveand extending along the Vbottom of said vessel, and means for rotating said shaft.

2. A corn popper as claimed in claim 1, including an angularly extending arm on the upper end of said shaft above said bar.

3. A corn popper as claimed in claim 1,` including an angularly extending arm on the upper end of said shaft above said bar, and said vessel having a cover and rotatable means mounted on said cover for operating said shaft.

4. A corn popper as claimed in claim l, including an angularly extending arm on the upper end of said shaft above said bar, and said vessel having a cover and rotatable means mounted on said cover for operating said shaft, said operating means comprisin a second shaft journaled in said cover, sai 10i second shaft having anangl-llarly extendir arm below said cover arranged to ooact wi the arm of 'said vessellshaft. l

5. A corn p including an angularly extending arm on the upper end of said shaft above said bar, said vessel having; a cover and rotatable means mounted on said cover for operating said shaft, said operating means comprising a second shaft journaled in said coverandhaving an arm projecting outwardly and downwardly from its inner end, and a said arm extending lower than t e arm of said vessel shaft.' s

6. A cornpopper as claimed in claim 1,

including yielding means tending to hold said shaft downward.

In testimony whereof, I hereunto setv my A' hand.
